Darklord alongside Lord Light is one of the two creators of Valhalla, a world the two intended to be an utopia. After leaving the world of Dem ruled by their friend Lord Lucifer they succeeded at creating the utopia they desired in the past. However, after their deaths the aftereffects of creating the utopia led to the rise of the Imperium and its two Imperius, who would rule it with an iron fist.

The ThreeTimeMaidens are servants of both him and Lord Light, who they left in the Orgel room of Lucifer's Dark Palace to continue their duties and left Time Chains with them. He would write two letters: one in Dem's past and the other in the Dark Temple that would be read in the future by Akira and Lucifer. After defeating the final boss he will appear alongside Lord Light to offer Akira and Jin three choices: rebirth (New Game+ keeping all stats and demons), to continue adventuring, and rest (being sent to the title screen and starting over from the last save). Choosing to continue adventuring will have him bring Lena back to life.

Dark Lord is a S-Rank BattleNet opponent in Light Version who appears after winning 71 S-Rank battles. Said to be Akira before transformation, he watches over Jin as he grows. After 15 defeats he will give a Uroboros and 20 defeats a Jormung
